Performance Tests
PDH Transmit/Receive Jitter Amplitude Accuracy
Check the Received Jitter Accuracy is within the limits in Table 3-5.
24 Return the TX MODULATION SOURCE to INTERNAL.
25 Check the Jitter accuracy for each value in Table 3-5. In each case, set the HP
37718A Rate and Spectrum Analyzer Center Frequency to the value given in
column 1 of the table (Set the HP 37718A PATTERN to ALL ONES and the
JITTER AMPLITUDE to minimum after each change of Bit Rate). Set the
HP 37718A Jitter Modulation Frequency and Amplitude to the values given in
columns 2 and 3 of the table. Fine-tune the amplitude to obtain the lowest carrier
level on the Spectrum Analyzer display and check that the TX jitter amplitude
displayed on the HP 37718A is between the limits given in columns 4 and 5 of
Table 3-5.
